The advent of pump-probe spectroscopy techniques paved the way to the exploration of
ultrafast dynamics of electrons and phonons in crystalline solids. Following photo-absorption …

This chapter reviews nonresonant, meV-resolution inelastic x-ray scattering (IXS), as applied
to the measurement of atomic dynamics of crystalline materials. It, in conjunction with a …

The coupled nonequilibrium dynamics of electrons and phonons in monolayer MoS2 is
investigated by combining first-principles calculations of the electron–phonon and phonon …

First-principles calculations of phonons are often based on the adiabatic approximation and
on Brillouin-zone samplings that might not always be sufficient to capture the subtleties of …

In most materials the electron–phonon (ep) scattering is far weaker than phonon–phonon
(pp) scattering, and the ep scattering is usually proportional to the ep coupling strength …

Doped semiconductors can exhibit metallic-like properties ranging from superconductivity to
tunable localized surface plasmon resonances. Diamond is a wide-bandgap semiconductor …

The adiabatic Born-Oppenheimer approximation is considered to be a robust approach that
very rarely breaks down. Consequently, it is predominantly utilized to address various …

Comprehending nonequilibrium electron–phonon dynamics at the microscopic level and at
short time scales is one of the main goals in condensed matter physics. Effective …

In model Hamiltonians, like Fröhlich's, the electron-phonon interaction is assumed to be
screened from the beginning. The same occurs when this interaction is obtained by using …

Inelastic scattering experiments are key methods for map** the full dispersion of
fundamental excitations of solids in the ground as well as nonequilibrium states. A …
